不同配方的保鲜剂对瓶插切花延缓衰老的效果研究

Effects of Different Preservativeson Delaying Senescencein Water-Cultured Cut Flowers

对香石竹切花瓶插期不同配方的效果进行了对比实验 .以蒸馏水为对照CK ,自制配方中的 5号 (4%S +5 0 0mg/LCA +2 0 0mg/L 8_HQ +0 .0 2 %CaCl2 +0 .0 2 %KCl)、8号 (5 %S +30 0mg/L 8_HQ +10 0mg/LB9)对香石竹的效果最好 ,可延长 6～ 8天 .以 4号美国保鲜剂为CK ,5号、8号对香石竹的保鲜期可延长 2～ 3天 .又对香石竹花瓣衰老过程中总糖、可溶性蛋白、SOD活性进行了测定 ,结果表示经过保鲜剂处理的其含量及活性均有明显的增加和增强 ,然后才呈下降趋势 ,从而延缓了下降速度 ,推迟了衰老过程 .

The paper deals with the effect of different fresh_keeperon several species of water_cultured cutting blooms.The results showth at 5th(4%S +5 0 0mg/LCA +2 0 0mg/L 8_HQ +0.0 2 %CaCl2 +0 0 2 %KCl)and 8th(5 %S +30 0mg/L 8_HQ +10 0 mg/LB9)fresh_keeper can significan tlye longate time of keeping fresh more than other culturesolutions,and the concentraion of total carbohydrate,total soluble protein and SOD activity in carnation petaltreated with 5th and 8th are higher than with other solutions.
